Refresh narrow window reveals with this high-quality 2 pack of White uPVC Capping Boards, designed...Refresh narrow window reveals with this high-quality 2 pack of White uPVC Capping Boards, designed to provide a clean, modern finish for smaller sills and frames. Each board measures 100mm in depth, 9mm in thickness, and 1.75 metres in length – making them ideal for compact windows, slim internal reveals, or tight working spaces. Perfect for home improvements, rental property updates or light refurbishments, these capping boards are made from tough, UV-resistant white uPVC that’s built to withstand everyday wear, sunlight, and moisture without fading or discolouring. The smooth, pre-finished surface eliminates the need for painting or ongoing maintenance – just cut to size and fix in place. With a 9mm slimline profile, the boards offer stability while remaining lightweight and easy to handle. Their shorter 1.75m length is especially convenient for working alone, in small rooms, or around awkward fittings where longer boards would be impractical. This 2 pack is ideal for tackling multiple windows or starting a consistent project where uniform results and durability are essential. Whether you're a tradesperson or tackling a DIY job, these boards offer a simple, effective upgrade to tired or damaged window sills. All parcels must be fully opened and inspected before signing. If signed without inspection, no damage claims will be accepted. This applies to DX Express and DX Freight.
